Terms of use

What this service is

CoilDesk is software. We are the vendor: you buy the subscription from Ellul Solutions Ltd directly, and there is no third party between us. We introduce you to nobody, we sell your details to nobody, and we take no commission from anyone for sending you anywhere. We aim to keep the service available at all times and to keep your data recoverable, but we do not guarantee uninterrupted access. If we plan work that will take the service offline we tell subscribers first. You can export your customers, jobs and documents at any time while your subscription is active and for 90 days after it ends.

How we are paid

You pay us, and that is the whole of how this business is funded: a monthly subscription to CoilDesk Pro, sold to businesses. Nothing on this site is an advertisement we are paid for, and no figure or recommendation here is influenced by a commission, because there is none. Price, renewal date and cancellation route are shown before you pay and stated again in your account. Purchase is offered to people acting for purposes related to their trade or profession. Where a consumer nonetheless buys, the statutory cancellation and digital content rights are honoured in full rather than excluded.

The free tools

The free calculators and document builders on this site are provided as working tools for HVAC professionals. Their output is arithmetic on the figures you enter. They do not replace a Manual J load calculation, a licensed inspection, a signed contract reviewed by your attorney, or your own judgement about a job.

No warranty

Nothing on this site is engineering, legal, tax or licensing advice. Equipment sizing produced by these tools is a first approximation for estimating and must be confirmed by a full load calculation before installation. Document templates are starting points, not attorney-drafted contracts for your state.
